Don’t even think about telling Cartoon Network and CNN to quiet down about bullying. The two Time Warner networks have made it their mission to speak up, this time with a special presentation of The Bully Effect on Sunday, April 28 at 5:30 and 8 p.m. (ET/PT).

The half-hour CNN original documentary will be presented commercial-free and abridged for family viewing, and features additional original content, including a candid discussion with CNN anchor Anderson Cooper, who hosts the documentary and is a recognized advocate for bullying prevention.

During and immediately following both telecasts, author and renowned bullying prevention expert Rosalind Wiseman will host an exclusive, live online chat at to answer questions from youth, parents and educators.

The networks also plan to make The Bully Effect as widely available to the public as possible. In addition to heavy on-air promotion of the broadcast, the documentary will be posted free on the StopBullyingSpeakUp.com website starting Monday, April 29 at 10 a.m., as well as on YouTube and it will be available through Video on Demand (VOD) for two weeks following the premiere telecast.

The Bully Effect continues Cartoon Network’s long-standing and vital conversation with kids and families about the need stop bullying, and it’s part of the network’s award-winning “Stop Bullying: Speak Up” initiative, which began in 2010.
